Feather microtome blades are single-use stainless steel blades for rotary and sledge microtomes, used to cut thin sections from paraffin-embedded tissue blocks in histology and pathology laboratories.
Each dispenser holds 50 low-profile blades (80 mm x 8 mm) with a 35° cutting edge, available in four models S35, R35, A35 and N35 so you can match the blade to your tissue type and sectioning workload.
Why Choose Feather Disposable Microtome Blades
- Consistent thin sections a precision-ground 35° edge produces smooth, even paraffin ribbons with fewer chatter marks and tears.
- Fresh edge every time disposable blades remove the need for knife sharpening and reduce cross-contamination between cases.
- Four models for different tissues choose the blade that suits routine biopsies, ribbon sectioning, very thin sections or harder tissue.
- Safe, fast blade changes the dispenser lets technicians load and change blades without handling the cutting edge.
- Standard low-profile format 80 mm x 8 mm blades fit the low-profile blade holders used on most rotary microtomes and cryostats.
Feather Microtome Blade Models Explained
S35 : Standard Blade for Routine Work and Biopsies
The S35 is the everyday low-profile microtome blade for routine paraffin sectioning and biopsy specimens, offering high sectioning quality with a short trimming time.
R35 : Durable Blade for Routine Ribbon Sectioning
The R35 is built for routine ribbon sectioning, with a reinforced edge treatment that improves edge strength and durability across long sectioning runs and firmer tissue.
A35 : Durable Blade for Very Thin Sections
The A35 is designed for very thin sections in both hard and soft tissue, making it a versatile choice for high-volume routine histology.
N35 : Blade for Hard Tissue
The N35 is intended for harder tissue that tends to dull standard blades quickly, helping maintain clean sections through dense specimens.

Handling and Use Tips
- Load blades directly from the dispenser into the blade holder to avoid touching the edge.
- Use the same blade clearance angle recommended by your microtome manufacturer.
- Trim with one section of the blade and move to an unused section for final thin sections.
- Dispose of used blades in an approved sharps container.
Frequently Asked Questions
What are Feather microtome blades used for?
They are used to cut thin, uniform sections from paraffin-embedded tissue blocks on rotary or sledge microtomes for histology, pathology and research slides.
How many blades are in each box?
Each dispenser contains 50 disposable stainless steel microtome blades.
What is the difference between S35, R35, A35 and N35?
S35 is the standard blade for routine work and biopsies, R35 is a durable blade for routine ribbon sectioning, A35 is designed for very thin sections in hard and soft tissue, and N35 is intended for hard tissue.
Are these high-profile or low-profile microtome blades?
All four models are low-profile blades measuring 80 mm long and 8 mm high, suited to low-profile blade holders.
Can Feather microtome blades be reused or resharpened?
No. They are single-use disposable blades and should be discarded in a sharps container once the edge is worn.
Do these blades work in a cryostat?
They can be used in cryostats that accept 80 mm low-profile disposable blades; check your cryostat’s blade holder specification before ordering.
